.net - Difference Between An F5 Browser Refresh And Postback?
Jul 22, 2010I am dynamically creating dragrids in different rows of an existing datagrid in asp.NET
My generated datagrids have a column which is TemplateColumn (a CheckBox Column).
In my parent datagrid, I have a template column with checkboxes. when I check or uncheck the value of the check box, the check_change method is called (autopostback is set to true), the dynamically generated datagrids lose the checked checkboxes (the checkboxes are all unchecked again). However, if i check any of the checkboxes of the child (dynamically generated) grids and press F5, it refreshes the page but still I have my checked checkboxes.
What's happening ?? how is post-back different from refresh F5??? understanding this might help me fix my problem here :DataGrid not being altered!
Refresh A Page Without Postback?
May 3, 2010There is a asp:Label in the page for showing message from server.
The message can be sent by server at any time.
I added a handler to update the Label's Text, like following:
void MessageReceived(object senders, EventArgsMessageReceived e)
{
lblMessage.Text = e.Message;
lblMessage.DataBind(); //To show the message
}
I am sure the break point of 'lblMessage.Text = e.Message;'' is hitted.
But the DataBind() seems not work, and the label isn't updated.

View 2 RepliesWeb Forms :: Refresh A Page On Postback?
Oct 12, 2010I've got a page with several gridviews that populate on page load. After user makes choices with radio buttons insid the gridview and presses submit I would liek the page to refresh and reload all gridviews.
postback page load loop and data doesn't get saved to the DB so I have to use If not Page.IsPostback then to avoid the loop.
After pressing submit, if I navigate to another page, then navigate back, I get the desired result I'm looking for a fresh reload.
how can I have the entire page reload fresh after the submit button is pressed? (it has to save data first then reload)
Refresh A Control On The Master Page After Postback?
Apr 12, 2010What i am trying to do here is to show a couple of validation messages in form of a bulletlist, so i have a Div on my master page containing a asp:bulletlist. Like this:
<div>
<asp:BulletedList ID="blstValidationErrorMessage" runat="server" BulletStyle="Disc">
</asp:BulletedList>
</div>
When i then click the Save button from any of my pages (inside the main contentPlaceHolder) i create a list of messages and give this list as datasouce like this:
blstValidationErrorMessage.DataSource = validationMessageCollection;
blstValidationErrorMessage.DataBind();
The save button is located inside an updatepanel:
asp:UpdatePanel runat="server" ID="UpdatePanel" ChildrenAsTriggers="true" UpdateMode="Conditional">
Nothing happens, i can see that the datasource of the bulletlist contains X items, the problems must arise because the Save button is inside an update panel and the elements outside this updatepanel (master page controls for example) is not refreshed.
So my question is, how do i make the bulletlist refresh after the postback?

AJAX :: Page Inside Update Panel Doesn't Refresh The Session Object After Postback Of Any Control
Oct 1, 2010I have many controls like dropdown, radiobuttonlist, etc on my page and I put all these controls inside the update panel so that the page doesn't look to be posting back when something is selected. Now the working on the page is very smooth. But the session object isn't getting refreshed even if I postback to the server and as a result even if the users are working on the page they are being sent to the login screen after 20 mins.
Is there anyway where I could put all the controls in update panel and still refresh the session after any postback(dropdown selection)

VS 2010 - Stop Master Page Redraw / Only Refresh Content Page?
Jul 20, 2012I am writing a web application which consists of a master page (header / menus) which does not change and content pages. When I do something like click on a button it causes a post back which is correct but this redraws the whole screen and becomes annoying because every post back and the whole screen flickers.
Is there a way to only refresh the content page?
